Determination of low level tritium concentrations in the Czech Republic for tritium tracing applications
2019
Abstrakt
Past tests of nuclear weapons in the atmosphere, nuclear energy facilities and tritium of natural origin are main sources of tritium in the environment. Thanks to its presence in environment and its favourable properties, tritium is used as a radiotracer.
Since stopping of atmospheric nuclear tests, tritium in precipitation has been decreasing towards natural levels below 1 Bq/L and precise analyses of low level tritium activities are necessary. This paper focuses on tritium in precipitation and ground water in the Czech Republic using liquid scintillation measurement with electrolytic enrichment.
